Key differences
Viagra belongs to Erectile Dysfunction (ED) while Celebrex belongs to Pain Relief Medications. Indications, mechanisms and target populations differ. The comparison is most useful when a clinician has mentioned both medications and the patient wants to understand where each fits.
Mechanism and action
Viagra: During sexual stimulation, nitric oxide is released in the corpus cavernosum and activates an enzyme that produces cyclic GMP. Celebrex: Celecoxib selectively inhibits COX-2, the inducible isoform of cyclooxygenase upregulated at sites of inflammation, while sparing the constitutive COX-1 that maintains gastric mucosal integrity and platelet aggregation.
When Viagra is preferred
The medication is indicated in adult men for the treatment of erectile dysfunction, defined as the inability to achieve or maintain a penile erection sufficient for sexual activity.
When Celebrex is preferred
Celebrex is approved in adults for the treatment of osteoarthritis, rheumatoid arthritis, juvenile idiopathic arthritis (in some markets), ankylosing spondylitis, primary dysmenorrhoea and acute pain.
